Abstract (en)
[origin: GB2503217A] Identifying a fault in an electric motor or generator by measuring a value of a first parameter associated with the operation of the electric motor or generator; increasing a counter value if the difference between the measured first parameter value, or a value derived from the measured value, and a second value is greater than a first predetermined value; decreasing the counter value if the difference between the measured first parameter value and the second value is less than the first predetermined value; and generating a signal indicative of a fault if the counter value exceeds a second predetermined value. The first parameter may be a current or voltage , or component of current or voltage, generated in a coil winding of the electric motor or generator. The second value may be a calculated value of the of the first parameter. The motor may be a permanent magnet synchronous motor.
